Laughing at 'Bill Gates is an asshole.' I've heard this anecdotally about everyone on your list, but not about him. People malign Microsoft and Windows, but please show me anecdotes about Gates the person being an asshole.
Also read Paul Allen's book -- specifically the part where Gates tried to screw Paul by diluting his stock.
